How to Avoid Alarm When Using a Spare Key to Open the Car Door?
1 Answers
On the spare key, due to the lack of a remote control mechanism, an alarm will sound after opening the car door. The alarm will stop once the engine is started with the key. Below are the reasons why a spare key triggers the alarm: 1. Whether it's the main key or the spare key, as long as the car is unlocked mechanically, the computer will consider it an intrusion. 2. If the car is locked with the remote but opened mechanically, it will be assumed as a forced intrusion and trigger the alarm. However, if you lock and open the car with the mechanical key, there won't be an alarm. This is a safety feature, and the alarm will be canceled after ignition. 3. The remote key locks the door and activates the alarm simultaneously, so using the spare key to open the door will trigger the alarm. Quickly inserting the key to power on after opening the door will stop the alarm.
